The environmental surveillance of the Risø environment was continued in July-December 2015. The mean concentrations in air were: 0.24±0.18 μBq m–3 of 137Cs, 2.71±0.88 mBq m–3 of 7Be and 0.28±0.20 mBq m–3 of 210Pb (±1 S.D.). The depositions by precipitation at Risø in the second half of 2015 were: 0.085±0.011 Bq m–2 of 137Cs, 607±30 Bq m–2 of 7Be, 59.6±4.2 Bq m–2 of 210Pb and 1.4±0.2 kBq m–2 of 3H. The average background dose rate (TLD) at Risø (Zone I) was measured as 42 nSv h–1 compared with 40 ± 2 nSv h–1 (±1 S.D.) in the four zones around Risø.
